JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Practice Selecting Elements

Posted by Alex Owen

<a id='link'> let navlinks = document.querySelectorAll('#link'); I don't understand why this isn't working. Thanks.

I am unable to figure out why adding an id to the <a> or <li> tags inside the <nav> tags and then selecting using document.querySelectorAll('#link'); isn't working. I may have misunderstood what the task is asking me to do.

Many thanks,

Alex

This challenge is about practicing selecting elements as they are. You should not make any changes to the HTML file, it is just provided for you to examine. Using querySelectorAll is still a good idea, you might try a descendant selector with it.

Also, it's not valid to use the same ID on more than one element on a page. All ID's must be unique.
